The Leng check list (1920) records under Scotochroa, which is a distinctly American genus established by Leconte in 1874, two species, S. atra Lec. and S. basalis Lec. Scotochroa buprestoides Kirby (described in 1837 as a Xylita) is listed under atra, indicating it as either a synonym or as being questionable as a valid species. The Csiki Catalogue of the Serropalpidae (1924) lists one species, atra, under Scotochroa with buprestoides given under this and with basalis as a variety. The Supplement of the Leng list (1927) records basalis as a variety of atra. The general question as to the species in this group seems to warrant a review of the genus with a key to the species.
